No. 765,439 Claimspriority, application Austria Oct. 7, 1957 2 Qlaims. (Q1. i39-93) Thepresent invention relates to heddles for harness frames and refers inparticular to a heddle having hookshaped ends for loom harness frames.Heddles of this type in stacks may he readily removed from the harnessframes and mounted thereon with comparative ease, whereby, however, isexperienced a serious drawback in that the stacks of heddles whendetached fall apart, as the heddles are not interconnected.

The present invention aims to eliminate the abovementioned drawback andis essentially characterized in that the heddles at each of their twoends and in the direction of the plane formed by the filed or strungheddles, comprise at least one aperture by means of which the heddlesare strung on an independent filing or stringing element, such aperturebeing in addition to the normal openings for the heddle guidnig railsand the warp threads.

Various forms of the invention are shown by way of example in thedrawing, in which- FIGS. 1 to 4 show in elevation heddles havinghookshaped ends.

In the drawing, the heddles only are shown with one of the hook ends andwith part of the heddle shaft.

In FIG. 1, the heddle 1a at one end comprises a hook 2a which isengageable in a corresponding U-shaped groove of a guide rail 3 which,for example, is rigidly connected to the shaft-supporting bar or isintegral therewith. At 4, hook 2a is welded or brazed to heddle shaft1a.

At the end of hook 2;; adjacent the heddle shaft there is provided anaperture in the form of an oval hole 5. A similar hole is provided inthe lower hook (not shown). The heddle is filed or strung through thetwo holes 5 on two wires or bars 5a.

In FIG. 2, a rectangular or square opening 6 is provided in the heddleend adjacent the heddle shaft 1b. The heddle is strung through the twoholes 6 on two wires or bars 6a.

In FIG. 3, a keyhole-shaped perforation 7 is provided on the end of hook20 adjacent heddle shaft 10. The latter consists of a circular wirewhich is rigidly connected to hook 2c such as by brazing. Here also,heddle 1c is strung on two wires or bars 7;; through the upper and thelower (not shown) perforations 7.

In FIG. 4, the heddle M is similar to that shown in FIGS. 1 and 2, andthe aperture in the outer end of hook 2a, i.e. the end adjacent theheddle shaft, is disposed in the form of a keyhole 8, a similar holebeing provided also on the lower hook. The filing wire or bar isdesignated by 8a.

The holes 5 to 8 serve in principle for stacking and holding togetherthe heddle with other heddles which also are provided with similar holesin the hook end, on filing elements such as wires, bars, profiled laths5a to 10a, when bundles or packs of heddles are removed from the harnessframe or supplied thereto as to a frontal plane assembly. In this way,entire heddle packs filed on the wires may be supplied to or removedfrom the harness frame in units as a frontal plane assembly without anyrisk of falling apart.

I claim:

1. A weaving heddle comprising a heddle shaft with a U-shaped hook endand a perforation in the hook end adapted to be filed on a wire so thata plurality of heddles may be removed as a frontal plane assembly fromor inserted in a harness frame as a unit, said U-shaped hook endcooperating with a similarly-shaped guide rail when the heddles aremounted in the harness frame.

2. A weaving heddle according to claim 1, in which the perforation isdisposed entirely on the end of the heddles.
